How does the horizontal recoil stack?

I understand that horizontal recoil is all about moving my aim point to a random point in a certain interval. But after that, will that random point be the new center point of the interval? So the horizontal recoil will actually stack and hit rate will decrease continuously as I keep full auto shooting. Also I would like to know that if 1st shot recoil multiplier affects horizontal recoil. thanks!

With this, I'll rid MGO3 of infestation. Sans bad gameplay MGO3 will be torn asunder. And then it shall be free. People will suffer, of course - a phantom pain.

Reddit and Konami will rewrite the records... And I will be demonized in human memory. But... The thirst for good gameplay that I have planted will infest MGO3. No one can stop it now. The Rebalance Mod will unleash that thirst unto the future.

That answers my further question! Because I was simulating 10 rounds LMG burst using Hitrater. The hit rates after minimum spread achieved keep dropping continuously, and that doesn't match in game performance. I was not aware of this "horizontal recoil maximum" because it is not listed in the symthic weapon stats. May I know where "horizontal recoil maximum" is in the data browser? It impacts a lot to at least LMGs. Thank you.
